shared operation by multiple life vest container devices 10a,
wherein the control and/or regulation unit 78a is provided for an
aircraft seat bench with at least one further aircraft seat (not
shown), wherein the control and/or regulation unit 78a may be
arranged in another region of the aircraft seat 10a or on the at
least one further aircraft seat. Alternatively, it is conceivable
that the control and/or regulation unit 78a is arranged inside the
life vest container 24a. The control and/or regulation unit 78a is
configured to capture an electric and/or electronic signal and to
send an output signal to a checking system 80a (cf. FIG. 1). The
first electric and/or electronic sensor unit 52a is configured to

[0051] It is conceivable that the control and/or regulation unit
78a is also configured as a part of an inflight entertainment
module and/or as a part of an aircraft seat adjustment module. The
control and/or regulation unit 78a is configured to determine,
whether there is a change of at least one of the three
characteristics. The output signal comprises a dataset, which
features information about the three characteristics. Additionally,
the dataset features information about the date of a correct
installation of the life vest unit 12a in the accommodation space
36a. As a result, a date of a scheduled replacement and/or a manual
inspection of the life vest unit 12a can be viewed advantageously.
Additionally, the dataset features information regarding a possible
removal of the life vest unit 12a from the accommodation space 36a
as well as a subsequent, correct or incorrect, re-insertion in the
accommodation space 36a. The checking system 80a is configured for
receiving the output signal, for data interpretation and for
presentation of a monitoring result. The monitoring result is
embodied as an outcome of a safety check of the life vest container
device 10a. The checking system 80a is at least partly arranged in
the aircraft. It is conceivable that the checking system 80a is
embodied as part of a maintenance, repair and/or overhaul system,
wherein the output signal is provided for planning of a manual
check and/or a replacement of the life vest device 10a on the
aircraft seat 14a.
[0052] The monitoring device 44a comprises two output units 82a,
84a (cf. FIG. 1). The output units 82a, 84a each are configured to
output the output signal. A plurality of life vest container
devices 10a are monitorable by means of the output units 82a,
84a.
[0053] A first output unit 82a is embodied as a screen unit. The
screen unit is accessible by a cabin crew of the aircraft. The
screen unit is part of the checking system 80a. The screen unit is
embodied as a portable tablet computer. Additionally or
alternatively it is conceivable that the screen unit is embodied as
a permanently installed screen, which is arranged in the aircraft
cabin of the aircraft. The permanently installed screen is arranged
on the aircraft seat 14a, for instance as a passenger screen, which
is provided for an inflight entertainment system, or on a cabin
wall, for instance on a cabin wall in a galley or on a cabin wall
in a region of a door of the aircraft. The first output unit 82a is
configured to show if the life vest container device 10a meets the
predetermined state value of the determined states. The screen unit
presents the output signal as a symbol relating to specific
aircraft seats 14a. The symbol is embodied as a check mark or as a
cross. The check mark appears if all determined state values
correspond to the predetermined state value. In the present case
the check mark appears if all state values are "false". The cross
appears if at least one of the determined state values of the three
characteristics does not correspond to the predetermined state
values. In the present case the cross appears if at least one state
value is "true".
[0054] The first output unit 82a shows a listing 86a of all
aircraft seats 14a which are arranged in the aircraft cabin (cf.
FIG. 1). For clarity, only four aircraft seats 14a are listed in
the listing 86a. The aircraft cabin comprises a first row with
aircraft seats 14a with seat numbers "1A" and "1B" (not shown). The
aircraft cabin comprises a second row with aircraft seats 14a with
seat numbers "2A" and "2B" (not shown). As shown on the first
output unit 82a the aircraft seats 14a with seat numbers "1A", "1B"
and "2B" have a successful safety check regarding the life vest
container device 10a. The aircraft seat 14a with seat number "2A"
has a not successful safety check regarding the life vest container
device 10a. A manual check of the life vest container device 10a of
the aircraft seat 14a with seat number "2A" has to be performed. It
is conceivable that further information about the safety check can
be retrieved by the output unit 82a, for instance which
characteristic has changed compared to the required condition.
Additionally, it is conceivable that individual passenger
information can be retrieved via the first output unit 82a, for
instance food and/or beverage preferences, frequent flyer status
and/or nationality. In principle, the way of representing the
output signal may differ from the shown embodiment. For instance,
the aircraft seats 14a may be displayed in a top view of the
aircraft cabin instead of the listing 86a.
[0055] A second output unit 84a comprises an optical and acoustical
element 88a that is arranged in an aircraft seat region (cf. FIG.
1). The second output unit 84a is configured to create a
combination of visual and acoustic outputs if the life vest
container device 10a deviates from a predetermined condition. The
optical and acoustical element 88a is arranged on the aircraft seat
14a. The optical element 88a is configured for presenting the
output signal traffic-light-like. The optical element 88a presents
the output signal traffic-light-like with three colors. The colors
are green, yellow and red. The output unit is configured to show if
the life vest container device meets the predetermined state value
of the at least one state. The optical element 88a is embodied as a
light-emitting diode. Additionally, it is conceivable that the
optical element 88a is configured to produce a flashing light if
the life vest container device 10a deviates from a predetermined
condition. It is conceivable that the optical element 88a is
embodied as a smart textile, which is integrated into an outer
fabric of the aircraft seat 14a. The acoustical element 88a is
embodied as a loudspeaker, which is configured to sound an alarm if
the life vest container device 10a deviates from the predetermined
condition.
[0056] FIG. 4 shows a method 90a for an operation of the life vest
container device 10a in a schematic view. The method 90a features a
method step 92a and a further method step 94a. In the method step
92a, the life vest container device 10a gets checked by means of
the monitoring device 44a. The characteristics are monitored in the
method step 92a. A manipulation of the life vest unit 12a and of
the life vest container 24a is captured via an electric and/or
electronic signal. A change of the characteristics due to a
manipulation is detected in the method step 92a via at least one
electric and/or electronic signal. In the method step 92a, the
states of the life vest container device 10a are monitored. In the
method step 92a, the control and/or regulation unit 78a captures
the at least one electric and/or electronic signal from the
electric and/or electronic sensor units 52a, 54a, 56a. The control
and/or regulation unit 78a sends an output signal to the checking
system 80a and to the output units 82a, 84a. In the further method
step 94a, the output units 82a, 84a output the output signal
visually and acoustically, in particular to the cabin crew. In the
further method step 94a, if the life vest container device 10a
deviates from the predetermined state value, the output signal will
change. Subsequently to the further method step 94a, the method
step 92a gets repeated. The method 90a is automatically repeated at
least every 60 seconds. It is conceivable that the method 90a can
also contain intermediate method steps and/or further method steps
which are not part of the invention.
[0057] FIGS. 5 to 10 show three further embodiments of the
